Diameter: 89mm-127mm 

Processing Type: Forging

Face design: Flat;  Convex;   Concave

Top hammer bit Face Features:

 Flat Face---This kind of top hammer drill bit face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.

Concave Face---The all-round application bit face is special for medium hard and homo-generous rock formations. Good holes deviation control and good flushing capacity.

Convex Face---For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor holes deviation control.
